Mechanical Draft Cooling Tower

A mechanical draft cooling towers, also known as a mechanical draft tower, is a cooling tower ventilated by wind, which is the main equipment of circulating water evaporative cooling. Mechanical draft tower is widely used in petroleum, chemical, metallurgical and other industries.

The mechanical draft cooling tower includes a bottle type cooling tower, square counter flow cooling tower, square cross flow cooling tower and closed circuit cooling tower.

Types of Mechanical Draft Cooling Tower

Square Cross Flow Cooling Tower (AH)

Square Counter Flow Cooling Tower(AF)

Square Counter Flow High Temperature Resistant Cooling Tower(AFG)

Square Counter Flow Non-basin Cooling Tower(AFW)

Round Counter Flow Cooling Tower(AB)

Round Counter Flow High Temperature Resistant Cooling Tower(GAB)

Big Metal Structure Square Counter Flow Cooling Tower(AD-NG)

Big Metal Structure Cross Flow Cooling Tower(AD-HG)

Closed Circular Counter Flow Cooling Tower(AFC)

Closed Circular Cross Flow Cooling Tower(AHC)

Difference Between Natural and Mechanical Draft Cooling Tower

The natural draft cooling tower makes use of the chimney operation of the cooling tower. The air flow is caused by the temperature difference between the air inside and outside the cooling tower. While mechanical draft cooling towers use fans to make air flow.

Advantage of Mechanical Draught Cooling Tower

The advantages of mechanical draft cooling tower are compact structure, small volume, light weight, convenient installation, not affected by external wind, reliable cooling effect; less loss of cooling water blowing, higher cooling efficiency, high water spraying density, less one-time investment.

Mechanical Draft Cooling Tower Working Principle

The mechanical draft cooling tower uses power-driven fan motors to force or draw air through the tower. Induced draft, a mechanical draft tower with a fan at the discharge at the top, can pull air up through the tower. The fan enables to induce hot moist air out the discharge.
